如何部署linux服务器监控shell脚本

1、查看主机网卡流量
#!/bin/bash
#network
#MikeXu
while : ; do
time=’date +%m”-”%d” “%k”:”%M’
day=’date +%m”-”%d’
rx_before=’ifconfig eth0|sed -n “8″p|awk ‘{print $2}’|cut -c7-’
tx_before=’ifconfig eth0|sed -n “8″p|awk ‘{print $6}’|cut -c7-’
sleep 2
rx_after=’ifconfig eth0|sed -n “8″p|awk ‘{print $2}’|cut -c7-’
tx_after=’ifconfig eth0|sed -n “8″p|awk ‘{print $6}’|cut -c7-’
rx_result=$[(rx_after-rx_before)/256]
tx_result=$[(tx_after-tx_before)/256]
echo “$time Now_In_Speed: “$rx_result”kbps Now_OUt_Speed: “$tx_result”kbps”
sleep 2
done
2、系统状况监控
#!/bin/sh
#systemstatsh
#MikeXu
ip=1921681227
top -n 2| grep “Cpu” >>/temp/cputxt
free -m | grep “Mem” >> /temp/memtxt
df -k | grep “sda1″ >> /temp/drive_sda1txt
#df -k | grep sda2 >> /temp/drive_sda2txt
df -k | grep “/mnt/storage_0″ >> /temp/mnt_storage_0txt
df -k | grep “/mnt/storage_pic” >> /temp/mnt_storage_pictxt
time=`date +%m””%d” “%k”:”%M`
connect=`netstat -na | grep “21923814830:80″ | wc -l`
echo “$time $connect” >> /temp/connect_counttxt
3、监控主机的磁盘空间,当使用空间超过90％就通过发mail来发警告
#!/bin/bash
#monitor available disk space
SPACE=’df | sed -n ‘/ / $ / p’ | gawk ‘{print $5}’ | sed ’s/%//’
if [ $SPACE -ge 90 ]
then
fty89@163com
fi
4、监控CPU和内存的使用情况
#!/bin/bash
#script to capture system statistics
OUTFILE=/home/xu/capstatscsv
DATE=’date +%m/%d/%Y’
TIME=’date +%k:%m:%s’
TIMEOUT=’uptime’
VMOUT=’vmstat 1 2′
users=’echo $TIMEOUT | gawk ‘{print $4}’ ‘
LOAD=’echo $TIMEOUT | gawk ‘{print $9}’ | sed “s/,//’ ‘
FREE=’echo $VMOUT | sed -n ‘/[0-9]/p’ | sed -n ’2p’ | gawk ‘{print $4} ‘ ‘
IDLE=’echo $VMOUT | sed -n ‘/[0-9]/p’ | sed -n ’2p’ |gawk ‘{print $15}’ ‘
echo “$DATE,$TIME,$USERS,$LOAD,$FREE,$IDLE” >> $OUTFILE
5、全方位监控主机
#!/bin/bash
# check_xush
# 0 /home/check_xush
DAT=”`date +%Y%m%d`”
HOUR=”`date +%H`”
DIR=”/home/oslog/host_${DAT}/${HOUR}”
DELAY=60
COUNT=60
# whether the responsible directory exist
if ! test -d ${DIR}
then
/bin/mkdir -p ${DIR}
fi
# general check
export TERM=linux
/usr/bin/top -b -d ${DELAY} -n ${COUNT} > ${DIR}/top_${DAT}log 2>&1 &
# cpu check
/usr/bin/sar -u ${DELAY} ${COUNT} > ${DIR}/cpu_${DAT}log 2>&1 &
#/usr/bin/mpstat -P 0 ${DELAY} ${COUNT} > ${DIR}/cpu_0_${DAT}log 2>&1 &
#/usr/bin/mpstat -P 1 ${DELAY} ${COUNT} > ${DIR}/cpu_1_${DAT}log 2>&1 &
# memory check
/usr/bin/vmstat ${DELAY} ${COUNT} > ${DIR}/vmstat_${DAT}log 2>&1 &
# I/O check
/usr/bin/iostat ${DELAY} ${COUNT} > ${DIR}/iostat_${DAT}log 2>&1 &
# network check
/usr/bin/sar -n DEV ${DELAY} ${COUNT} > ${DIR}/net_${DAT}log 2>&1 &
#/usr/bin/sar -n EDEV ${DELAY} ${COUNT} > ${DIR}/net_edev_${DAT}log 2>&1 &
放在crontab里每小时自动执行：
0 /home/check_xush
这样会在/home/oslog/host_yyyymmdd/hh目录下生成各小时cpu、内存、网络，IO的统计数据。如果某个时间段产生问题了，就可以去看对应的日志信息，看看当时的主机性能如何。
